This invention relates to dispensing mechanism and provides for the delivery of lubricating oil in measured quantity.

Motorists usually purchase one quart of lubricating oil when supplying the oil tank or reservoir of the motor. and to meet this demand service stations provide quart bottles of oil. This is expensive both at the dispenser, because of the number of bottles l0 required and the time consumed in the lling thereof, and to the motorist, due to the shortage resulting from the handling of oil in this manner.

In accordance with the present invention,

a barrel or other container for the oil in bulk may be located at any convenient point and connected by pipeto the predetermined point of delivery. A dispensing hose connec ted with the service pipe is provided with 2O a handle which also constitutes a receptacle for delivering the required amount of oil to be dispensed, one quart or any other determinate quantity. rlhis combined handle and measuring' receptacle is elongated and '5 shaped for Convenient handling and is provided at opposite ends with controllingv valves, the inlet valve controlling a vent for the escape of air displaced by the inflow of oil into the handle when lilling it after each delivery of the oil therefrom.

While the drawings illustrate a preferred embodiment of the invention, it is to be understood that in adapting the means to meet specific needs and requirements, the design may be varied and such other changes in the minor details of construction may be resorted to within the scope of the invention as claimed, without departing from the spirit thereof.

For a full understanding of the invention and the merits thereof reference is to be had to the following description and the drawings hereto attached, in which:

Figure l is an elevational view illustrative of an embodiment of the invention.

Figure 2 is an enlarged sectional view of the combined handle and measuring vessel.

Figure 3 is a detail sectional view on the line 3-3 of Figure 2.

Figure 4 is a detail view of a portion of the head of the barrel or container, showing the plug for closing the filling opening 'formed therein.

Corresponding and like parts are referred to in the following description and 'designated in the several views of the drawings by like reference characters.

Referring to Figure l of the drawings,

.the numeral l designates a wall of the enclosed structure of a service station for supplying motor vehicles with fuel and lubricating oil. The numeral 2 designates a barrel or container' within the structure or otherwise conveniently positioned and adapted to hold the oil in bulk to be dispensed. An underground pipe line 3 connects the barrel or container 2 with a dispensing hose l. A suitable meter 5 is located in the length of the pipe line 3 for measuring the quantity of oil flowing therethrough in a given time. A post 6 or like support is located at a determinatepoint and supports the dispensing hose 4: when the same is not in active service.

A plug 7 closes a .filling opening formed in Vfitted for supplying the container with air under pressure whereby the oil may bepositively expelled therefrom.

A device 9 is littedto the delivery end of the dispensing hose d and constitutes both a handle and a vessel for measuring the amount of oil to be dispensed at each operation. The device 9 is elongated and hollow and is .usually of a capacity to hold one quart of oil which is the amount generally Ydispensed at each operation. The part 9 is of such formation as to be conveniently grasped in the hand. A dispensing faucet .l0 is fitted to the delivery end of the combined handle and measuring vessel and may be of any determinate construction. A valve l1 of any type or structure is applied to the receiving end of the device 9 and controls the supply of oil thereto. The valve 11 is formed with a vent 1:2 which, when the valve is opened, provides an escape for the air displaced by the oil iiowing into the part 9. When the valve 1l is closed, the vent 12 is likewise closed to prevent escape of oil from the com- ,Zine

bined handle and measuring vessel and from the dispensing hose.

When the plug 7 is removed the container 2 is supplied with oil through the fillin opening and after the container has receive the required amount of oil to be supplied thereto, the plug 7 is replaced and compressed air is supplied to the container by means of the valve 8 and in consequence of this pressure the oil is forced from the container through the pipe line 3 and hose pipe 4 into the part 9, When the valve 1l is opened.

After the part 9 has been lled the va'lve'l'l is closed, and when it is required to dispense the oil contained in the part 9, the Valve l0 is opened,'the oil flowing from the part 9 through the valve 10 into the crank case, oil tank or reservoir of a motor vehicle in a manner well understood. Upon closing the valve l0 andopcning the valve ll, the part 9 is again supplied with oil which is dispensed at the next operation, as Will be readily understood.

Having thus described the invention, What `I claim is:

l. Means for dispensing measured quantities of liquid comprising a tube adapted to have one end connected with a source of supply, a vessel to holdy a determined quantity 0f liquid consisting of an elongated hollow body of a diameter to be grasped in a hand and constituting a handle, a valve connecting the inner end of said body With said tube and including av casing and a control plug to be turned from an open to a closed position, companion air passages being formed in the casing and plug and adapted to register when the plug is in an opened position, and a faucet connected with the outer end of said body.

2. Means for dispensing measured quantities of liquid comprising a tube adapted to have one end connected with a source of supply, a vessel to hold a determined quantity of liquid consisting of an elongated hollow body of a diameter to be grasped in a hand and constituting` a handle, and flow controlling means at the inner and outer ends of said body, the flow controlling means at the inner end of the body including an air vent opened and closed by adjustment of the flow controlling 'means With which it is associated.

In testimony whereof I affix my signature.
